The wifi will not work on my new Inspiron and fails to work even after repaired.  I have now been through 3 sessions with Dell Support.  Each time they resolve the problem, and I finally can get online.  However, the next time I sign on again after the laptop has been asleep or shut down, the same problem is back.  Now the folks at Dell Support want me to ship it to them so they can run a full diagnostic and repair.  I've already lost several hours dealing with this and still have NEVER been able to use my laptop longer than one session.  It's still well within the warranty period but past the 30-day return window, and I have already thrown away the box.  Can someone tell me how to do a return and get a refund?
